Engineering Evaluation of Age Life Extension, T-10 Harnesses, Risers and T-10 Troop Chest Reserve Parachute Canopies

摘要

A textile and engineering evaluation was conducted by the U.S. Army Natick Laboratories on T-10 troop type Parachute Harnesses, Risers and Chest Reserve Parachute Canopies, obtained from world wide samplings of 6 to 10 year age classes. Despite strength losses in the nylon webbing harness and riser and nylon canopy materials, sufficient residual strength remains in the various components to justify extension of service life above the 10-year limitation now empirically imposed on the items. An additional period of 3 years of age life appears to be justified for harnesses and risers and an additional age life of 2 years for the T-10 reserve parachute canopy. (Author)
